Over on the Minute Physics YouTube channel they recently did a series of videos narrated by physicist Sean Carroll based on his latest book The Big Picture that covers such interesting topics as What is the Purpose of Life? (hint: it has nothing to do with a god) In one video they cover cause and effect and Carroll describes how it's an emergent phenomena when looking at the universe at macro scales. That means it isn't really fundamental, as I've covered here before. Go check out the video series and enjoy.
